More specifically, it relates to an external skin treatment composition and antimicrobial agent capable of being preferably used for external skin treatment compositions, cleansers, food, daily necessities, etc., including a diol compound or its derivative having superior antimicrobial activity to a broad range of microorganisms and safe to the human body, maintaining sufficient preservability, while remarkably improved in usability and safety.

As fields of use, the present invention may be utilized for various types of external skin treatment compositions in the fields of pharmaceuticals, quasi-drugs and cosmetics (including various preparations used for human and other animal use), specifically application to lotion, milk lotions, creams (including ointments), sun screens, foundations, oils, packs, soaps (including medicated soaps), body soaps, lipstick, manicure preparations, eye cosmetics, perfumes, facial cleansers, oral hygiene products (toothpastes, mouthwashes, etc.), deodorants (underarm odor, foot odor, etc.), bath agents, shampoos, rinses, hair tonics, hair sprays, hair dyes, etc. may be mentioned. Further, application to medical use cleansers meant for disinfecting and cleaning medical equipment or diseased parts, household cleansers for sterilizing and washing teblewares, cleansers for the food industry, etc. may be mentioned. Further, use for antimicrobial treatment of textile products (sheets, apparel, etc.), food packaging film, plastic, wood, daily necessities, etc., various types of oral medications, nonwoven fabrics such as sanitary napkins, wet tissue or paper towels, sterilizing cloth, or oral compositions (gum, candies, etc.) or fishpaste products such as Japanese kamaboko, chikuwa, or animal products such as sausages, ham, western confectioneries, Japanese confectioneries, noodles such as raw noodles, boiled noodles, Chinese noodles, Japanese udon noodles, Japanese soba noodles, spaghetti, seasoning such as soysauce, sauces, gravies, foods, juices, soups, and other general foods and beverages can be mentioned.

BACKGROUND ART

Up to now, as antimicrobial agents and preservatives for food, pharmaceuticals, cosmetics, etc. for suppressing the proliferation of microorganisms, sorbic acid, dehydroacetic acid, and their salts, paraoxybenzoic acid derivatives, etc. have been often used, but these have problems in terms of safety, and therefor the amounts of addition and foods to be added are restricted (for example, the upper limit of use of sorbic acid and its salts in food is 0.2%, dehydroacetic acid and its salts can only be used for cheese, butter and margarine and the upper limit of use of sodium methyl paraoxybenzoate in cosmetics is 1.0%).

Further, to suppress the proliferation of microorganisms, invasion by microorganisms has been suppressed by the physical method of the skin or mucuous membrane in the body or by the chemical method such as the distribution of bactericidal substances or mucous. Further, resistance has been given against microorganisms invading the body through inhibition of adhesion by immunogloblin, the phage action by phagocytes, the lysis action of lysozymes, innate aspecific resistance to infection and immunoresponse to specific pathogenic bacteria, etc.

However, if the infective power of the microorganism becomes higher than the resistance in the organism, there is the risk that the organism will show symptoms of infection, for example, pyoderma and other infectious dermititis due to Staphylococcus aureus, food poisoning, blood poisoning, conjunctivitis and iritis due to Bacillus subtilis, urinal tract infection, etc. diarrhea due to E. coli, periodontitis due to Actinobacillus etc., cavities due to cavity-causing bacteria, and further acne, dandruff, ichiness accompanying dandruff, and various other symptoms due to Propioni bacterium acnes and Pityrosporum ovale, etc.

Therefore, various chemicals have been used up to now for the prevention or treatment of infection internally and externally. The antibiotics or antimicrobial agents and preservatives accounting for the majority of these are indeed strong in effect, but have problems in safety. Serious care is required in their use. More useful substances, in terms of efficacy, safety, etc. have been sought.

In recent years, safe external skin treatment compositions soft on the skin have been sought. On the other hand, external skin treatment compositions have to stress shelf life. Consideration of preservative action is required. Many external skin treatment compositions in fact secure preservability by use of a preservative constituted by a paraoxybenzoic acid ester, also known as “parabens”.

However, when using a paraben as a preservative, sometimes some sensitive users will exhibit skin irritations such as stinging at the time of use, and therefore, the usability was also unsatisfactory. Using no paraben to prepare the external skin preparation composition is of course possible, but in that case securing preservability requires the use of small single-use containers, the provision of a backless mechanism in a tube container, or other complicated means. This lacked general usability.

DISCLOSURE OF THE INVENTION

Ethanol, glycerol, 1,3-butylene glycol, POE (60) hydrogenated castor oil, methyl paraben are dissolved (i.e., an alcohol phase). The aqueous phase and the alcohol phase were mixed.

Test Method for Usability

A panel consisting of 10 women having a sensitive skin, who had an irritation feeling when an external skin treatment composition containing paraben was used. The test was carried out in such a manner that each paneller used the above external skin treatment composition twice a day for 1 week and, based upon the satisfactory degree and the presence or absence of the skin irritation of each paneller, the usability is evaluated based upon the following 4-rank standards. The number of the persons having irritation feeling was also counted.

A: Number of paneller having good feeling is 8 or more

B: Number of paneller having good feeling is 5 to less than 8

C: Number of paneller having good feeling is 3 to less than 5

D: Number of paneller having good feeling is less than 3

Test Method for Judging Preservability

To 30 ml of the samples of the Examples and Comparative Examples, microbials in a liquid were inoculated and then the change in the number of the microbial was checked after 2 weeks from the inoculation by a smear culture method. The inoculated microbials were as follows.

Mould: Aspergillus niger ATCC16404. Inoculation amount 10⁴ cfu (colony forming unit)/g

Yeast: Candida albicans ATCC10231. Inoculation amount 10⁵ cfu/g

Bacteria: Escherichia coli ATCC8739. Inoculation amount 10⁶ cfu/g; Staphylococcus aureus ATCC6538. Inoculation amount 10⁶ cfu/g; Pseudomonas aeruginosa ATCC15442. Inoculation amount 10⁶ cfu/g

The preservability (or antisepsis) was evaluated used upon the changes in the number of the microbials and the results were classified to the fallowing 4 ranks.

A: All of the mould, yeast and bacteria are decreased to 100 cfu/g or less within 1 week.

B: All of the mould, yeast and bacteria are decreased to 100 cfu/g or less within 2 weeks.

C: Either of the mould, yeast or bacteria remain in an amount of 100 cfu/g or more even after 2 weeks.

Usability Test and Preservability Test

The lotion having the formulation shown in Table IV-1 was prepared according to the following preparation method and subjected to the usability and preservability (antisepsis) tests.

Preparation of Lotion

To the purified water, 3-Phenoxy-1,2-propanediol was added for Examples IV-1, IV-2 and IV-3 and 3-benzyloxy-1,2-propanediol was added for Examples IV-4, IV-5 and IV-6. Citric acid, trisodium citrate, trisodium edetate are dissolved therein (i.e., an aqueous phase). Ethanol, glycerol, 1,3-butylene glycol, POE (60) hydrogenated castor oil, methyl paraben are dissolved (i.e., an alcohol phase). The aqueous phase and the alcohol phase were mixed.

Test Method for Usability

A panel consisting of 10 women having a sensitive skin, who had an irritation feeling when an external skin treatment composition containing paraben was used. The test was carried out in such a manner that each paneller used the above external skin treatment composition twice a day for 1 week and, based upon the satisfactory degree and the presence or absence of the skin irritation of each paneller, the usability is evaluated based upon the following 4-rank standards. The number of the persons having irritation feeling was also counted.

A: Number of paneller having good feeling is 8 or more

B: Number of paneller having good feeling is 5 to less than 8

C: Number of paneller having good feeling is 3 to less than 5

D: Number of paneller having good feeling is less than 3

Test Method for Judging Preservability

To 30 ml of the samples of the Examples and Comparative Examples, microbials in a liquid were inoculated and then the change in the number of the microbial was checked after 2 weeks from the inoculation by a smear culture method. The inoculated microbials were as follows.

Mould: Aspergillus niger ATCC16404. Inoculation amount 10⁴ cfu (colony forming unit)/g

Yeast: Candida albicans ATCC10231. Inoculation amount 10⁵ cfu/g

Bacteria: Escherichia coli ATCC8739. Inoculation amount 10⁶ cfu/g; Staphylococcus aureus ATCC6538. Inoculation amount 10⁶ cfu/g; Pseudomonas aeruginosa ATCC15442. Inoculation amount 10⁶ cfu/g

The preservability (or antisepsis) was evaluated used upon the changes in the number of the microbials and the results were classified to the following 4 ranks.

A: All of the mould, yeast and bacteria are decreased to 100 cfu/g or less within 1 week.

B: All of the mould, yeast and bacteria are decreased to 100 cfu/g or less within 2 weeks.

C: Either of the mould, yeast or bacteria remain in an amount of 100 cfu/g or more even after 2 weeks.

D: All of the mould, yeast and bacteria remain in an amount of 100 cfu/g or more even after 2 weeks.

As the preservability of an external skin treatment composition, those judged as “A” or “B” is acceptable. The results of the usability and preservability tests are shown in Table IV-1.
